Stress-induced Transformations in Ti-mo Alloys

Microstructure and Tensile Behavior of Laser Arc Hybrid Welded Dissimilar Al and Ti Alloys

Fiber laser-cold metal transfer arc hybrid welding was developed to welding-braze dissimilar Al and Ti alloys in butt configuration. Microstructure, interface properties, tensile behavior, and their relationships were investigated in detail. The results show the cross-weld tensile strength of the joints is up to 213 MPa, 95.5% of same Al weld. The optimal range of heat input for accepted joints...

Phase transition and ordering behavior of ternary Ti – Al – Mo alloys using in - situ neutron diffraction

Neutron diffraction has been used for in-situ investigations to elucidate the phase transformation behavior of two Mo-containing TiAl alloys with compositions of Ti-44Al3Mo and Ti-44Al-7Mo (in at.%). Five different phases are present in these alloys. These include three ordered phases at room temperature, namely a2, b0 and c and two disordered phases, a and b, which occur at higher temperatures...

Hot and Cold Tensile Behavior of Al 6061 Produced by Equal Channel Angular Pressing and Subsequent Cold Rolling

The full annealing AA6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ECAP) and cold rolling (CR) in order torefine its microstructure and to improve its mechanical properties. According to the results of hotand cold tensile tests, the combination of ECAP and CR significantly affected the final strengthand ductility of studied...

EFFECTS OF TENSILE STRENGTH ON FATIGUE BEHAVIOR AND NOTCH SENSITIVITY OF TI-6AL-4V

In this research, rotating bending fatigue test at minimum to maximum stress ratio of R=-1 was used for investigating the fatigue behavior of Ti-6Al-4V alloy. Both smooth and notched specimens, with elastic concentration factor, kt, of approximately 3.6 and 4.1 were used for this purpose.In addition, the effect of variation in ultimate tensile strength, UTS, on the fatigue behavior of this allo...
